It is a sensor with 4 legs, two of which belong to the receiver and two to the transmitter. It is more sensitive than the Cny70 sensor. Since it can perform operations such as line tracking, color separation, and object detection, it can be easily used in many robotic projects. When using it with Arduino, you need to put a resistor in between.
